GEORGE G. SCHRO EDER, OF WASHINGTON, DISTRICT OF COLUMBIA. STREET-CAR PROFULSIJON- Specification of Letters Patent.

Patented March 19 1907.

Application filed March 20,1906. Renewed June 28, 1906. Serial No. 323.863-

-T0 aZZ- whom, it may concern:

Be it known that I, GEORGE G. Sermon at Washington, in the District of Columbia, have invented new and useful Improvements in street Car Propulsion, of which the following is a specification. f

This invention has relation to street-car propulsion; and it consists in the novel construction and arrangement of its parts, as hereinafter shown'and described.

The object-of thisirivention is to provide a means for propelling cars, said means consisting of an engine (preferably of the rotary hydrocarbon type) located at each end of. the car, one engine adapted to beused for moving the car in one direction along the track and the other enginebeing adapted to move the car in the oppositedirection. Both of the said engines are alike in construction and are similarly connected to the front and rear car-axles, respectively. The gearing b etween the engine and the car-axle is of special construction and arrangement and is so arranged as to permit the car trucks and axles to describe a partial rotation with relation to the car-bod when going around curves. A means is al so provided to permit the carbody to move vertically with relation to the trucks, as when loading or, unloading, and

switches, or uneven track. Each end of the car is provided with a compartment in which an engine is located. The operator having charge of the engine also occupies the said 'compartm ent. Most of the gearing between the engine and the car-axle is located beneath the floor of the car-body, and conseuently does not occupy space in the body of t e can A means is provided for throwing the engine-shaft in gear with the gearing at will, and a means is provided for reversing the motion from theengine-shaft (which rotates continuously in one direction) with the car-axle. This latter means is for convenience in use for backing the car or for movingthe same for. short distances in either direction. v The car-body proper is also of special construction and arrangement, as will be hereinafter more particularly pointed out.

In the accompanying drawings, Figure '1 is an en inc 7.

a perspective View of a car with a portion of one end thereof broken away, showing the location of one engine. Fig. 2 is a horizon-,-

tal sectional view of the car-body, showing tional view of one end of the car, showing the location'of the engine and the transmissiongear. Fig. 5 is a side elevation, partly in section, of the gearing for transmitting motion from the engine-shaft to the car-axle. Fig. 6 is a top plan View of the gearing for horizontal lane.

The carody is provided at each end with an enginecompartment 1. compartment 2 occupies the ma or portion of the body of the car, and exten s from one l of the engine-eompartmentsl, toward the other engine-compartment. The said passenger-compartment 2 is separatedfrom the adjacent engine-compartment 1 by the platform 3. The freight-compartment 4 is lo cated at the end of the passenger-compartment 2, and the aisle 5 passes between the back of the freight-compartment 4 and the side of thecar-body and leads from the platform 6 into the passengcr-compartment 2.

The platforms 3 and 6 are provided with suitable steps at each side, as indicated, and the 'passengcnconipartment 2 is provided with seats and other accessories usually foundin conveyances of this character.

In each of the com artmcnts 1 is located The saic engines are of themtary ydrocarbon type, and any suitable construction of engine ((preferabl type) may be employs As tie engine proper forms no part of this invention, a descripto'n of itsconstruction'and operation is deemed unnecessary. .Each engine 7 is provided with an oil-tank 8, suitably located, The pipe 9 connects the tank 8 with the carbureter 10.

. The pipell connects the'carbureter 10 with the 'mixer' 12, and the pipe 13 connectsthe Thepassengerof such transmitting motion from the engine to the car-axle and Fig. 7 is a top plan view, partly in section, of a portion of thegearing and car t axle showingv the means for permitting the said axle to describea partial rotation in'a said mixer with the engine 7. The tank 5. earbureter 10, and mixer 12 may be of any suitable construction.

The shaft 14 of the engine 7 is provided at its end with the beveled gear-wheel 15. The shaft 16 extends vertically through the'fioor of the ear-body and is provided at its upper end with the beveled gearnvhecl 17, which meshes with the beveled gear-wheel 15. The said shaft. 16 is provided at its lower end with the beveled gear-wheel 18. Suspended from the body of the car is a short horizontal shaft 19, which is provided at one end with a bevaled gear-wheel 20, which meshes with' the gear-wheel 18. The other end of said shaft 19 is provided with the sliding disk 21 of the frietion-eluteh The lever 22 passes through the floor of the ear-body and engages at, its lower end the sliding disk 21 and is adapted to be operated from within the compartment 1. The disk 23 is located upon the end of the shaft 24. Said shaft 24 extends in alinement with the shaft 19. The said disk 23 is fixed upon the shaft 24 an-l is adapted to be engaged and disengaged by the sliding disk 21. The bracket 25 is attached to the under side. of the car-body, and one end of the shaft 24 is journaled in said bracket. The end of the shaft 24 within the said bracket 25 is provided with a beveled gear-wheel 26. The pin 27 is vertically located within the bracket 25, and upon said pin is located a sliding sleeve 28. The said sleeve 28 is provided with the beveled gear-wheels 2t) and 30. The bell-crank lever 31 is attached at one end to the sleeve 28 and is fulcrumed to the under side of the car-body. The rod 32 is at taehed to the other end of the said bell-crank lever 31 and at its opposite end is attached to the lower end of the lever 32 The said lever 33 extends vertically through the bottom of the. car-body, its upper end being in the compartment 1.

The shaft 34 is in alinen'ient with the shaft. 24. Theinner end ofthe shaft P4 isprovided with the beveled gear-wheel 35, and the outer end of the said shaft 34 is provided with the universal joint 36. The. upper end of the shaft 37 is attached to one of the members of.

the. universal joint 36, and the lower end of the said shaft 37- is provided with a feather 38. The feathered end of the shaft 37 enters the sleeve and is adapted to play longitudinally therein. V The lower end of the sleeve 39 is made solid and cylindrical and is jouri naled in the bearing 40. Said bearing 41') in turn s,journaled-.upon the, eollar 41, which surrounds the axle 42. At an intermediate point the sleeve 39 is provided with a beveled gear-wheel 43, which meshes with a beveled gear-wheel 44, attached to one end of the col- The ends of the opening through the I lar 4]. collar 41 are flared or enlarged in diameter, as at 45, so that the axle 42 may have a slight.- lateral swing within the said collar. The

axle 42 is provided with a feather 46, which causes the said axle to rotate with the collar 41. In place of the said feather 46 pins or other suitable means may be substituted, if desired.

From the above description of the construction of the gearing it will be observed that when the disk 21 is thrown into engagement with the disk 23 that the shaft 24 and its attachments will rotate with the shaft 19, which in turn gets its rotary motion from the engine-shaft 14 through the shaft 16. When the gear-wheel 29 is moved into engagement with the gear-wheels 26 and 25, the shaft 34 rotates in the opposite direction from the ro ta'tion of the shaft 24. When the gear-wheel 30 is moved into engagement with the gearwheels 26 and 35, the shaft 34 rotates in the same directior: as does the shaft 24.

As above described, the gear-wheels 2S) and 30 are operated through the lever 33. Both of the said gear-wheels cannot be in engagement with the gear-wheels 26 and 35 at the same time; but, indicated in Fig. 5. the said gear-wheels 29 and 30 are so spaced apart upon the sleeve 28 as to be both out of engagement with the gear-wheels 26 and 35. Thus the reversing of the motion from the engine-shaft 14 is accomplished. The engine-shaft rotates in one direction only.

As the body of the car elevates or depresses with relation to the trucks the feathered end of the shaft 37 moves in or out of the end of the sleeve 39, and thus the (li'lferenee in the relative distance between the body of the ear and the trucks is compensated for.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-' An improvement in ear propulsion eom prising a sleeve adapted to surround the axle of a car to rotate. the same, said sleeve being free to move longitudinally on said axle, the bore of said sleeve being constructed to permit the axle to swing horizontally, and means for rotating said sleeve.
